Archaeologists are hailing the discovery of an “extraordinary cache” of cannabis found in an ancient burial in northwest China, saying that the unique find adds considerably to our understanding of how ancient Eurasian cultures used the plant for ritual and medicinal purposes.

In a report in the journal Economic Botany, archaeologist Hongen Jiang and his colleagues describe the burial of an approximately 35-year-old adult man with Caucasian features in China’s Turpan Basin. The man had been laid out on a wooden bed with a reed pillow beneath his head.
